Dan is right on the mark here - and keep in mind here that there are folks with a lot of strong opinions on things. that's how this forum goes. it's rarely any kind of flame war, but occasionally feathers can get ruffled, and feelings hurt.
personally i'm also very impressed. from the experience of an educator with a lot of familiarity in Max and a little in PD, i would totally welcome any number of your excellent GUI objects into Vanilla (my favorite as i want to work with libpd) or Extended. as for the various other libraries and externals you've made, i will leave that for the experts to handle the issues of duplication. (i also agree a prepend object in vanilla would be wonderful however). i'm not discounting the wonderful GPLd work, GUI based and otherwise, done by so many contributors in pd-extended but it presents issues to less code-savvy people wanting to make iOS apps in PD.
in short, i think more work for Vanilla than can be turned into iOS apps through libpd is extremely welcome. so thumbs up from me! keep doing what you're doing.
best to all,
scott
